The effects of acetone vapour inter-layer processing on fused deposition modelling 3D printed acrylonitrile butadiene styrene

摘要

The characteristics of the interlayer bonding within 3D Printed objects is a fundamental feature determining the strength of the resultant object. This study set out to identify the opportunity for additional inter layer processing within 3D Printing. Inter layer processing is the addition of processes before a new layer can be printed upon a previous layer. Thirty Acrylonitrile butadiene styrene ASTM D638 Type IV dog-bone samples were generated using an UPBox Fused deposition modelling printer. These were segmented into five groups associated with exposure at 0%, 20%, 25%, 50%, and 100% printing intervals. Tensile testing was conducted through the utilization of an Instron 5967 and a Hitachi TM3030Plus Scanning electron microscope was used for topographical analysis of sample layer fusion/bonding. Samples showed a inversely proportional change in characteristics relative to inter-layer processing, namely an increase in processing decreased the ultimate tensile strength at elongation and decreased the distinguishable layering and cavities within the sample.
